Okay. I saw this one before, but only one time. And this appears again. Do it yourself Matcha.
It looks like a bottle of water with a green label over it. And that is what it basically is. A bottle of water. That is until you read the instructions on the back.
The bottle cap actually doubles as a container of matcha powder. When you twist it, the powder is released into the water. You must now shake this vigorously to mix things up.
You can see in the above photos the cap is actually a long tube that housed the Matcha.
On to the taste! I was actually expecting it to be much more bitter, more than the typical green teas available at the stores. But I was wrong, the bitterness was not there at all. At first I thought the tea was actually weak, not so! The flavor is subtle, but good: very leafy (as is the intention.) You taste the tea flavor, not the bitterness. Obviously the drink tastes very grainy as you just dumped a cap-full of tea leaf powder into it, but this only ads to the experience. I would definitely recommend this over purchasing the basic green tea bottle. The strange cap is more than just a gimmic.
The white cap can also be taken off with some elbow grease. This way you can see the powder storage mechanism: there is a plug at the bottom that “clicks” onto the green top, and pops off when you crack the top open.
